Muss ich erstmal wieder herausfinden, wie das genau geht...
Das ist recht simpel. Wenn der Treiber saa716x_ff mit dem Parameter video_capture=1 geladen ist, am Prompt ein "svdrpsend grab name.jpg" eingeben, dann sollte es eine Datei name.jpg mit dem Bildschirminhalt geben.
Code
"GRAB <filename> [ <quality> [ <sizex> <sizey> ] ]\n"
" Grab the current frame and save it to the given file. Images can\n"
" be stored as JPEG or PNM, depending on the given file name extension.\n"
" The quality of the grabbed image can be in the range 0..100, where 100\n"
" (the default) means \"best\" (only applies to JPEG). The size parameters\n"
" define the size of the resulting image (default is full screen).\n"
" If the file name is just an extension (.jpg, .jpeg or .pnm) the image\n"
" data will be sent to the SVDRP connection encoded in base64. The same\n"
" happens if '-' (a minus sign) is given as file name, in which case the\n"
" image format defaults to JPEG."
